If you're really wondering why different programming languages exist, the answer is simple: different use cases, and the influence of past languages. Bell Labs did the same by creating C, C++ and AWK. For any of the languages you mentioned, it's easy to find the motivation for their creation, either by Wikipedia or on official pages Why X?. Your uninformed rant sounded a bit lazy and naive (sorry, no offense intended). From the top of my head... Go was meant as a higher-level language than C where Python could not apply (bad performance, weak typing, no compilation, complex syntax); its wide adoption proves that kind of language was missing at the time. Dart was initially meant as an alternative to JavaScript, like CoffeScript, at a time where JS was less standard. Kotlin was not created by Google, and was meant as a light alternative to Java/JVM, with full compatibility, hence the adoption for Android which is JVM based. As far as I know, Swift and Rust aren't specifically tied to Google.
